PULLEY.

SPECIFICATION forming part of Letters Patent No. 318,686, dated May 26,1885.

Application filed January 522, 1885.

To aZZ whom it may concern.-

Be it known that 1, ROBERT W. BETTs, residing in Montclair, in thecounty of Essex and State of New Jersey, have invented certain new anduseful Improvements in Pulleys, of which the following is adescriptionin such full, clear, concise, and exact terms as will enable any oneskilled in the arts to which my invention belongs or to which it is mostnearly connected to make and use the same, reference being had to theaccompanying drawings, making part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of said drawings is a perspective View of a pulley having myinvention applied thereto, and Fig. 2 is a perspective view of a detailpart thereof.

This invention is intended as an additional improvement upon theimprovement in pulleys for which a patent was granted to me and WilliamHowie October 11, 1875, and reissued December 28, 1875, being numbered6,822 of reissued patents. That invention consists of a facing orcovering of paper applied, cemented, or glued to-the drawing-surface ofa pulley for the purpose of keeping it from slipping and increasing itsdrawing power.

My present invention consists of a facing or sheathing of wood or othersuitable material applied and glued or cemented to the paper facing, andhaving a paper facing or covering applied to the outside or surface ofthe wood sheathing, the object being to furnish a ready means ofenlarging the diameter of the pulley and for extending the width of itsdriving or belt surface.

In the practice of this improvement I apply the paper to the surface ofthe pulley substantially as described in the patent above alluded to. Ithen make segments of wood,

(No model.)

substantially as shown in Fig. 2 of the drawi ngs, of the desired lengthand thickness, and glue them to the paper surface of the pulley,covering its entire circumference with such segments. When the glue hasdried sufficiently to hold the segments firmly in place, I put thepulley in a lathe or other suitable apparatus, and turn down the woodsheathing to the designed width and diameter, after which I apply afacing or covering of paper to the surface of the wood sheathing in amanner substantially the same as that applied to the metal surface ofthe pulley. The rim of the metal pulley is illustrated by a, Fig. 1, thepaper facing by b, the wood segments by c, and the external papercovering by d.

In some cases in applying the segments of wood to the circumference ofthe pulley I cut creases or channels in them, as shown by f, Fig. 2, anddraw and glue the cords e e e in such channels, for the purpose of morefirmly holding said segments together and to the surface of the pulley.

Having thus described myinvention, I claim as new and desire to secureby Letters Patenttially as described.
